Leonard Berkowitz

Leonard Berkowitz (August 11, 1926 – January 3, 2016) was an American social psychologist best known for his research on altruism and human aggression. He originated the cognitive neoassociation model of aggressive behavior, which was created to help explain instances of aggression for which the frustration-aggression hypothesis could not account.

During that period, he also held visiting appointments at Cambridge, Cornell, Oxford, and Stanford Universities. At the time of death, he was a Vilas Research Professor Emeritus in the Department of Psychology at the University of Wisconsin–Madison. During his lifetime, including as recently as two months prior to his death, he authored of over 170 articles, books, and textbooks on psychology. A ''Review of General Psychology'' survey, published in 2002, ranked Berkowitz as the 76th most cited psychologist of the 20th century.

On January 3, 2016, Berkowitz died at Oakwood Village in Madison, Wisconsin after a brief undisclosed illness at the age of 89. Provided by Wikipedia
